IMPROVEMENT IN SELF-OILING AXLE-BOXES.

Specification forming part of Letters Patent No. 196,789, dated November 6, 1877; application filed May 21, 1877.

To all whom it may concern: I

Be it known that I, JAMES DAWB'ER, of Braidwood, county of Will, and State of Illi-' nois, have invented a new and useful Improvement in Self-Oiling J ournal-Box, of which the ing the axle, and the other contains cottonwaste. A passage connects the oil-chamber and the chamber containing the cotton waste, and a passage leads from the last-mentioned chamber to the journal-bearing. The whole is constructed so that when the car is dumped a quantity of oil flows from the oil-chamber to the cotton waste, from which it is supplied to the axle.

Referring to the drawing, A is the journalbox casting, whichis attached to the truckframe B in the usual way. In this casting the chambers a b are formed. The chamber a is wholly above the journal, at one side of the center of the casting, while the chamber 7) is partly below the upper side of the journal, in the other side of the casting. A passage, 0, connects the chambers a b, and a passage, d, leads from the chamber a to the bearing-surface of the box. a

The chamber a, in the present case, is filled with cotton waste; but this may be dispensed with without materially affecting the opera tion of the box.

The chamber bis provided with a cover, 0,

in which there is an aperture, f,- and a groove is cut in the truck-frame from this aperture beyond the end of the casting A, for filling the chamber 1) with oil. 7

' The operation of the oil-box is obvious. When the truck is dumped the box is tipped sufficiently to cause a small quantity'of the oil to run from the chamber 1) to the chamber a, from which it is gradually fed to the bearingof the axle.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent The journal-box casting A, provided with l the chambers a b and passages c d,- substantially as herein shown and described.

JAMES DAWBER.
